● The entire system’s electrical control cabinets utilize an indoor Rittal-style design with an IP40 protection rating. There are three control cabinets: cabinets 1 and 2 are MCC cabinets, and the final one is a PLC cabinet. This design effectively isolates interference between power and signal lines.
L'alimentazione principale dell'armadio elettrico è un sistema trifase a cinque fili con una tensione nominale di 380 V CA, una frequenza nominale di 50 Hz e una corrente di carico massima di 300 A.
Il filo nero all'interno dell'armadio è la linea di alimentazione AC380V, il filo giallo è la linea di controllo AC220V, il filo blu è la linea di controllo DC24V e il filo giallo-verde è la linea di terra.
● The main components inside the cabinet include a molded case circuit breaker, a miniature circuit breaker, an intermediate relay, an AC contactor, a frequency converter, and a PLC.
The ACS510 series inverter is used within the cabinet. This series is specifically optimized for fan and pump applications. Typical applications include constant-pressure water supply, cooling fans, subway and tunnel ventilators, and more.
The cabinet features an advanced operation panel, which connects to the internal inverter and allows for start/stop operation and displays operating status information.
The cabinet is equipped with a multi-function electric meter, providing real-time monitoring of three-phase voltage, current, and other parameters.
